LIQUID-COOLER.

I Specification of Letters Patent.

Patented June 18, 1912.

Application filed February 24, 1912. Serial No. 679,789.

To all whom it may concern:

Be it known that we, WILLIAM FAHRMAN, FRANK FAHRMAN, and DANIEL BoL'roN,citisons of the United States, residing at Joplin, in the county ofJasper and State of Missouri, have invented certain new and usefulImprovements in Liquid-Coolers, of which the following is a.specification, reference being had to the accompanying-drawin s.

This invention relates to liquid coolers and more particularly to arefrigerating device for beer, soda water and similar bevera es.

The invention has for its primar object the provision of improved meansor supporting a plurality of pipe coils within a reservoir and injuxtapositionto an ice containing basket, the convolutions of therespective coils being so arr'angedthat the ice water within thereservoir may freely flow around and between the same.

Another object of the invention resides in the provision of improvedmeans for mounting the ice basket and the pipe hangers within thereservoir, said hangers being oonuected at their upper ends to thebasket and acting in the nature of braces or supports therefor.

A'st-ill further object of the invention resides in the provision of adevice of the above specified character which is simple, durable andefficient in construction, and may be manufactured at comparativelysmall cost.

lVith the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described i. and claimed, and illustrated in theaccompanying drawings, in which-- Figure l is a side elevation of aliquid cooler embodying the present invent-ion partly broken away toshow the construction of the reservoir walls; Fi 2 is a section taken onthe line 22 of Fig. 1; Fig. 3 is a section taken on the line 3'-3 ofFig. 2; and Fig. 4 is a section taken on the line l t of Fig. 3.

Referring in detail to the drawings 5 designates a suitable tank orreservoir which as shown is of rectangular form, though it will beunderstood that this,' reservoir may 1 any preferred shape. The wal a?ervoir consist of the outer and d walls 6 and 7 which are prefera ofwood, the space between said walls being filled. with a suitable heatnon-conducting granulated material indicated at 8, cork preferably beingemployed. The wall 7 is provided with an inner lining 9 of zinc or othersheet metal. This tank or reservoir is provided with a hinged top 10 sothat access may be readily obtained to the interior thereof. The bot-tomof the reservoir is preferably of the same construction as the side'andend walls thereof and tothe same the upper ends of suitable standards orsupporting legs 11 are attached.

Within the reservoir 5 an ice container or basket generally indicated bythe numeral 12 is arranged, and said basket is constructed from aplurality of longitudinal and trans verse metal straps l3 and'14respectively which are securely riveted or otherwise fastened togetherat their intersecting. points. These crossed metal straps form an openframe through which the water fromthe melting ice contained within thebasket escapes and gradually accumulates within the reservoir 5. Thetransversely disposed straps 14 have the upper ends of their verticalportions laterally extended as indicated at 15 and are securely boltedor otherwise fastened as indicated at 16 to the side walls of thereservoir. Certain of the longitudinal straps 13 which have their otherends vertically disposed to form the end walls of the basket are alsolaterally extended as shown at 17 and secured to the end walls of thetanker reservoir by means of the bolts 18. Hanger bars 19 are rigidlybolted as at 20 to the bottom of the tank or reservoir 5,

the upper ends of these hanger bars being laterally extended asindicated at 21 and secured in a similar manner to the side and endwalls of the reservoir. These hanger bars are disposed between the wallsof the ice basket and the walls of the reservoir and are provided uponeach of their faces with a plurality of rack plates 22. The curved rackplates 22 on one side of the hanger bars are disposed alternately withrelation to the series of rack plgtes on the opposite side of said bar.Similar hanger bars 19 are secured to the laterally disposed upper endportions of the strap plates of the ice basket and are flanged at theirlower ends, said flanges resting upon the bottom wall of the r'voir 5.-These latter hanger in position and thereby obviate liability ofbreakage of the metal strap plates by the great weight of the icecontained in said basket. It will be obvious that if desired the hangerbars 19 alone may be depended upon to support the pipe coils, the firstnamed bars 19 being eliminated.

It will be appreciated that by providing the two series of rack platesupon the hanger bars, the cooler may be utilized for the refrigerationof two beverages differing in character, and in the drawings I haveshown the inner and outer pipe coils 23 and 2A respectively which extendfrom the main liquid tanks or receptacles. As an illustration of one ofthe uses of the invention, the outer pipe coil 24 maybe connected to abeer keg containing light beer while the inner pipe coil is connected tothe keg containing dark beer. The ends of these pipe coils are extendedthrough one of the side walls of the tank or reservoir 5 adjacent to theends thereof and to the same suitable draw-oflt' cocks or faucets 25 areconnected. The inlet pipes for the coils 23 and 24 are disposed throughone of the end walls of the tank adjacent to the upper end thereof asshown in ,Fig. 1.

To the bottom of. the tank or reservoir 5 a suitable drain pipe 26 isconnected, and the end of said pipe may be closed by a suitable stopperor plug 27 so that the water from the melting ice can be retained withinthe reservoir until it reaches a desired depth. To the drain ipe 26which leads to a sewer main, astan pipe 28 is connected, and a pluralityof lateral branch pipes 29 extend through one of the end walls of thereservoir and are adapted to drain the water therefrom at variouslevels. Valves 30 are arranged in the stand pipe 28 to closecommunication between said pipe and the lateral pipes 29. The upperlaterally disposed pi e 29 extends through the casing wall at the upperends of the pipe coils and constitutes an ovcrfiow pipe through whichthe water may find an outlet when it is allowed to continuouslyaccumulate therein.

From the foregoing it is believed that the construction and manyadvantages which accrue to our improved cooling' apparatus will beapparent. By means of the same beer or other beverages may be veryquickly cooled in their passage through the pipe coils, the coils beingof sufficient extent to insure the cooling of the liquid to a lowtemperature n its passage th'erethrough from the main tank or receptacleto the faucets 25. By

mounting the ice basket and the pipe hangers within the reservoir intheman r spec1-v fied, an extremely strong, rigid an durable structureis secured, said hangers and basket mutually serving to support theweight. of the ice and the pipe coils. The invention is extremely simplein construction andmay 3 of the reservoir,

be manufactured at a nominal cost so that the same may be produced on areduced scale for individual service. While we have shown and describedthe preferred construction and arrangementof the various parts, it willbe understood that the invention is susceptible of considerablemodification without departing from the essential feature or sacrificingany of the advantages thereof.

Having thus described the invention what is claimed is 2-.

1. In a liquid cooler, the combination with a tank or reservoir, of anice container'arranged within said reservoir and rigidly secured to thewalls thereof, a plurality ofhanger bars connected at their upper endsto the container and resting at their lower ends upon the bottom of thereservoir to serve as additional means of support for the container, anda plurality of pipe coils extending through the walls of said reservoirand'mounted upon the hanger bars.
